USN focuses on side-scan sonar for countermine operations

22 May 2018

The US Navy (USN) will depend on side-scan sonars and related synthetic aperture sonar (SAS) technology to conduct mine countermeasures (MCM) operations using Littoral Combat Ship (LCS) mission packages, said the service in a recent report to Congress.

“Effective minehunting systems rely heavily upon the deployment of a side-scan sonar, which primarily searches for bottom mines on the sea floor, combined with a fully integrated volume search sonar,” the USN said in its report on SAS technologies for the LCS MCM package, released on 21 May.

“SAS technology provides improved minehunting performance for the side-scan sonar,” the report said. “These fully integrated minehunting systems drastically reduce the total amount of time needed to search large bodies of water in order to support combatant commander operational MCM timeline requirements.”
